Paper folding method and device for manufacturing filter cartridges

ABSTRACT

A paper folding method and device for manufacturing filter cartridges. The device consists of a paper feeding mechanism and a paper receiving-folding mechanism. The paper receiving-folding mechanism is mounted oppositely by two groups of conveyer belts ( 7, 8 ) provided With a plurality of protruding parallel sheets. Papers are fed by the paper feeding mechanism in accordance with the paper folding height and speed. Two groups of protruding parallel sheets in the receiving-folding mechanism grip the filter paper alternately to receive and fold the paper. The paper folding height can be adjusted by adjusting the relative height of the protruding parallel sheets in the two groups of conveyer belts of the receiving-folding mechanism. The conveyer belts can move in a direction rapidly with an increasing speed. The device can manufacture different specification paper folding of all kinds of filter cartridges, and the production efficiency can be improved.

The present invention relates to a paper folding method and device for manufacturing filter cartridges, and particularly relates to a paper folding device capable of conveniently manufacturing filter cartridges with all kinds of specifications.

BACKGROUND

Currently, paper folding production of filter (air filter, fuel filter and oil filter) cartridges only adopts reciprocating type paper folding machines and drum type paper folding machines.

DISCLOSURE OF THE INVENTION Technical Problems

However, as inserting sheets conduct reciprocating motion for receiving paper, the reciprocating; type paper folding machines is limited in speed. Moreover, the adjustment for the inserting sheets is very time-consuming when the folding height is changed.

During work, filter paper passes through the front paper feeding roller set (3) at a specified position by the paper guide stick (1), and then enters the paper receiving-folding mechanism formed by the intersection of protruding parallel sheets of the lower conveyer belt (7) and the upper conveyer belt (8), the intersection height of the protruding parallel sheets of the lower conveyer belt (7) and the upper conveyer belt (8) is adjusted to conform to an order, and a paper feeding speed is also adjusted to conform to a paper receiving speed. Meanwhile, paper folding is heated and sized by using the heating device (15). In this way, the circumference of the paper feeding roller and the protruding parallel sheets of the conveyer belts all conduct linear motion, and their speeds can be adjusted to be very high, so that the paper folding efficiency can be very high. in addition, as the filter paper folding height can be controlled only by adjusting the intersection height of the protruding parallel sheets of the lower conveyer belt (7) and the upper conveyer belt (8), the operation is convenient.
